Got into a situation last night and need some help clarifying:

Red Squadron X-Wing with R2 Astromech (All speed 1 and 2 manoeuvres are considered green manoeuvres) takes a critical hit which said "All hard turns are considered red" (or words to that effect). Hard turns are Speed 2(?) on an X-Wing so....

Which statement would take precedent? Or do they cancel each other out?

The maneuver would be red. RRG P 10 explains this:

Quote

If two game effects conflict in changing the
difficulty of a maneuver, the effect that makes the
maneuver more difficult takes priority. The other
effect is ignored.

Cheers.

This isn't upgrade vs. damage it is negative vs. positive and as Smuggler points out Negative wins.

There is no generic "negative wins" rule.

There is a very specific rule that says an effective that an effect that makes a maneuver more difficult trumps one that makes it easier. But that only applies to maneuver difficulties.
